  • Patent number: 4310490
    Abstract: A method and apparatus for enriching the iron carbonyl content of a recycle gas stream produced in an iron carbonyl decomposition or reaction process to enable reuse of the recycle gas stream in the iron carbonyl decomposition or reaction process by cooling the recycle gas stream, adding carbon monoxide to the recycle gas stream, compressing the recycle gas stream to a pressure of about 20 to about 38 atmospheres under conditions suitable to prevent substantial decomposition of residual iron carbonyl, and contacting the compressed gas stream at a temperature of about 65.degree. to about 160.degree. C. with a reduced iron containing material in the presence of hydrogen sulfide under conditions suitable to produce substantially condensed iron carbonyl.
    Type: Grant
    Filed: September 29, 1980
    Date of Patent: January 12, 1982
    Assignee: Pentanyl Technologies, Inc.

  • Patent number: 4192676
    Abstract: Copper is recovered from copper salts selected from the group consisting of copper chlorides, copper oxides and copper oxychlorides by reducing the finely divided solid copper salts with hydrogen under turbulent conditions at a temperature greater than the melting point of elemental copper.

  • Patent number: 4013457
    Abstract: A process is disclosed for separating cuprous chloride from a solution comprising cuprous chloride and one or more of a number of metal impurities, the process comprising crystallizing the cuprous chloride from the solution in the presence of copper as cupric chloride in a concentration of at least about 20 grams per liter.

  • Patent number: 3973949
    Abstract: A pollution-free process for the recovery of high purity zinc from zinc containing material including sulfide ores which provides for maximum conservation and re-use of reagents, the process consisting of chlorinating the materials either with ferric chloride or chlorine gas followed by selective removal of metals other than zinc by standard procedures, such as, lead chloride crystallization, cementation, etc. to produce a solution containing essentially only zinc chloride and ferrous chloride. To enhance the purity of the zinc end product zinc chloride is separated from the ferrous chloride solution with a zinc selective extraction agent from which the zinc chloride is stripped with sodium chloride solution in a sodium chloride stripping circuit followed by precipitation of zinc as the carbonate.

  • Patent number: 3972711
    Abstract: A process is disclosed for separating cuprous chloride from a solution comprising cuprous chloride and at least one metal chloride compatible with the solubility of cuprous chloride, the process comprising crystallizing the cuprous chloride from the solution in the presence of cupric chloride in an amount such that the cupric chloride to compatible metal chloride mole ratio is at least about 0.1.

  • Patent number: 3972795
    Abstract: There is provided a membrane-free axial flow electrolytic cell in which the anodes and cathodes are perforated and lie transversely of a conduit through which an ion containing and conducting medium is pumped. This device is especially useful in the electrolytic recovery of metal values from acid leach solutions from low grade ores, e.g., copper, and for the carrying out of electrochemical reactions such as the production of sodium hypochlorite or sodium chlorate from NaCl.
